' 1 Thisinventionhas for its object to produce alcoholic spirfs ii'ombeer, wash, wort, or any other liquid that` will answer the purposey y, "lhe improvements relateto the evaporating-chami ber, its form, which .allows/"the liquid to present a y larger evaporatiugsurthce Lin proportion to its quantitythanhas heretofore beenattained; also, to adevicetonpreventingthe wasln from ,boiling over into ,l `the spirit-condenser, and for returning the wash cooled .to the eva'porutmg-chamher, when, through excess of heat,'it has boiled up out of the same; also, to a dei vice which prevents thespirits ii-om entering the coollng-chamber, and at the sametime allows the wash to escape therefrom. In the drawingl A is' the still, which isof' ordinary construction,

B-V is. the `evaporating-chamher,v placed next above and communicating with the still.

Heretotore, cvaporatingchambers have been made in simple tubular shape-which exposes but a `compar `atively small surface ofthe wash to evaporation. vMy

i chamheris an .improvement over `this form, in that it is made of double conicaltbrm, tapering outward from the point of its junction with the still to the point b, thencecylindrical'to the point b', and thence tapering chamber allows the wash to spread out and expose a` i' `larger evaporatingsurfacethan itcould present in a tube, thus accelerating theprocess `of distillation and `diminishing thealiability of `.boiling over.

As a further preventiveof this latter mischief', I

' provide a conical receiver,` O, "within an inclosingchamber, Op', which `receiver communicates, by an inclinmlppe,- c, with the vapor-tube a, and bya pipe,

` c', with the evaporating-chamber B.

' The inclosing-chamber O' receives a constant sup'- plyotcold water.l Should the wash hecomegso heated as to rise in the vapor-tube ato vthe height of the pipe git-cannot tal to rundown -the latterand enter theV y ',lheA lower cone returns meal' and other sedimenttolt-he still. The expansion ofthe conical receiver, where it iscooled vby the surrounding water.

` Then the latter becomes heatedby the wash in the receiver, it risesto the top of' the chamber and runs out bythe spout d.' Y

Within the evaporatiug-chainber, over the lower mouth of the pipe c', is a valve, e, which is made sufciently heavy to retain theliquid inthe receiver until someconsiderable quantity of it accumulates there and becomes cooled. v v

' When .overbalancem the valve e opens and allowslthe wash in the receiver to flow back into the evaporating-chamber. In this manner all tendency to boil over is corrected, which being the case, the still may be filled full without exposing the process to one of the dangers to which it has rheretoforebeen` liable.

Moreover, the wash is by this means prevented from` entering the spirit-condenser through the tube a, and thus deteriorating the quality of the high wines.

Fronrthe foregoing it is evident that, hy my appa-v i ratus, I am enabled vto make more and better spirits than can. be made by thefordinary process, and in much less time. f

There is a collapse-valveh, in the side of the pipe c, which admits external air, when, by condensation in the receiver O, avacuum' is formed within the pipe. i 'There is also a safety-valve, i, in the top of the receiver O, for the purpose of letting off vapor when it brings a dangerous pressure upon the inside of the receiver.

'Having thus described my invention, What I claim .as new, and desire to secure by Letters Patent, is

1.4 The evaporating-chamber B, constructed as described, for the purpose of exposing an increased e\ apt mating-'surface of' the wash. 2. The cooling-receiver O, combined with its inclos ing-chamber, and with the evaporating-elnunber, and `withthe vapor-tube, in the manner described and for the purpose of preventing boiling over of the wash.

3. rlhe weighted valve e, constructed and operating as set forth.

To the above specification of my invention I have signed my handthis 5th day of February, 1870.
